ENERGY IS EVERYTHING

Reading about a new operating system can tell you only so much about it: After all, Windows Vista had far more features than XP, [CONJUNCTION] fell far short of it in the eyes of many users. To judge an OS accurately, you have to live with it. Over the past ten months, I've spent a substantial percentage of my computing life in Windows 7, starting with a preliminary version and culminating in recent weeks with the final Release to Manufacturing edition. I've run it on systems ranging from an underpowered Asus EeePC 1000HE netbook to a potent HP TouchSmart all-in-one. And I've used it to do real work, not lab routines. Usually, I've run the OS in multiboot configurations with Windows Vista and/or XP, so I've had a choice each time I turned the computer on: [MODAL] I opt for Windows 7 or an
older version of the OS? The call has been easy to make, because Win 7 is so pleasant to use.
So why wouldn't you want to run this operating system? Concern over its performance is one logical reason, especially since early versions of Windows Vista managed to turn PCs that ran XP with ease into lethargic underperformers. The PC World Test Center's speed benchmarks on five test PCs showed Windows 7 to be faster than Vista, but only by a little; I've found it to be reasonably quick on every computer I've used it on - even the Asus netbook, once I upgraded it to 2GB of RAM. (Our lab tried Win 7 on a Lenovo S10 netbook with 1GB of RAM and found it to be a shade slower than XP; for details see "Windows 7 Performance Tests.").
Here's a rule of thumb that errs on the side of caution: If your PC's specs qualify it to run Vista, get Windows 7; if they don't, avoid it. Microsoft's official hardware configuration requirements for Windows 7 are nearly identical to those it recommends for Windows Vista: a 1-GHz CPU, 1GB of RAM,
16GB of free disk space, and a DirectX 9-compatible graphics device with a WDDM 1.0 or higher driver. That's for the 32-bit version of Windows 7; the 64-bit version of the OS requires a 64-bit CPU, 2GB of RAM, and 20GB of disk space.
Fear of incompatible hardware and software is another understandable reason to be wary of Windows 7. One unfortunate law of operating-system upgrades - which applies equally to Macs and to Windows PCs - is that they will break some systems and applications, especially at first.
Under the hood, Windows 7 isn't radically different from Vista. That's a plus, since it should greatly reduce the volume of difficulties relating to drivers and apps compared to Vista's bumpy rollout. I have performed a half-dozen Windows 7 upgrades, and most of them went off without a hitch. The
gnarliest problem arose when I had to track down a graphics driver for Dell's XPS M1330 laptop on my own - Windows 7 installed a generic VGA driver that couldn't run the Aero user interface, and as a result failed to support new Windows 7 features such as thumbnail views in the Taskbar.
The best way to reduce your odds of running into a showstopping problem with Windows 7 is to bide your time. When the new operating system arrives on October 22, sit back and let the earliest adopters discover the worst snafus. Within a few weeks, Microsoft and other software and hardware companies will have fixed most of them, and your chances of a happy migration to Win 7 will be much higher. If you want to be really conservative, hold off on moving to Win 7 until you're ready to buy a PC that's designed to run it well.
Waiting a bit before making the leap makes sense; waiting forever does not. Microsoft took far too long to come up with a satisfactory replacement for Windows XP. But whether you choose to install Windows 7 on your current systems or get it on the next new PC you buy, you'll find that it's the unassuming, thoroughly practical upgrade you've been waiting for ? flaws and all.

In today’s society, measurements are used for many applications not only in industry and science but also in our daily life. There are measurements involved such as when buying petrol or foodstuff from the shop or energy from utilities; when trying to keep within the speed limits when driving your car; in health analyses when doctors diagnose and treat on the basis of blood pressure measurements; or when authorities make measurements to control the pollution in the air that we all breathe. Common to all these situations is that the measurement results need to be accepted (with confidence) by society. If not, the result is repeated measurements, disputes and legal actions. In most cases, the consumer or even the user of the measuring instrument does not personally have either the knowledge, the opportunity or the equipment to check whether the measurement that is so important for us is correct or not. In most countries, the legislature therefore has decided to set accuracy requirements for these types of measurements; most commonly, measurements in trade are regulated, but increasingly, also those within the health and environmental sectors.
Ongoing harmonization in Europe has become more and more the first reference point for authorities in the establishment of requirements for measurements, as requirements for new
measuring instruments are stated in directives; the most important of these directives being the Measuring Instrument Directive (MID) and the directive on Non-Automatic Weighing Instruments
(NAWI). For many of the instrument categories covered by the directives, there is a national possibility to select the prescription of different accuracy classes for different applications, and furthermore, to decide on what maximum permissible errors (MPEs) to apply in-service.
